Source Naturals Taurine 500 mg 120 tabs

Taurine is a crystalline, free-form amino acid. It is a soothing, inhibitory neurotransmitter and plays a major role in stabilizing the heartbeat and electrical activity of the nerves. Taurine is also necessary for the proper functioning of the sodium-potassium ATP-ase pump, which regulates the ion balance between the cells and the extracellular fluid that surrounds them. This critically important pump actually uses 7-40 percent of the ATP energy our bodies produce.
